MOTOR.

SPECIFICATION forming part of Lette-rs Patent No. 644,580, dated Marsh 6, 1906.

Application filed December 14, 1897. Serial No. 661,797. (No model.)

T0 all whom if may concern:

Be it known that I, WILLIAM CLINE, a citizen of the United States, residing at Lancaster, in the county of Lancaster, State of Pennsylvania, have invented certain Improvements in Motors, of which the following is a specification. I

This invention relates to improvements in gravity-motors, a special adaptation of the principles of which is covered in Letters Patent No. 605,854, dated June 21, 1898, for an improvement in elevators; and the object of this invention is to impart motion by means of a weight or traveler moving down a pivoted lever having its free end depressed by said weight or traveler.

The invention consists in the construction and combination of the various parts, as hereinafter fully described, and then pointed out in the claims.

In the accompanying-drawings, which form a part of this specification, Figure l is a side elevation of a device embodying my invention in its most simple form; Fig. 2, a front view of the lever and the traveler when said lever is lowered, as shown by broken lines -in Fig. 1. Fig. 3 is a side elevation of a device in which the power is transmitted from the traveler through atrain of gearing; Fig. 4, a top plan view of the construction shown in Fig. 2, and Fig. 5 a vertical section on broken line 5 5 of Fig. 3.

Similar letters indicate like parts throughout the several views.

Referring to the details of Figs. l and 2, A A indicate the posts of the supporting-framework, and A2 A3, respectively, the upper and lower horizontal members thereof. On opposite sides of post A are upwardly and outwardly projecting arms a, in which is journaled a rock-shaft b, having rigidly secured thereto an end of a lever B, the sides b whereof form rails for the wheels d of the traveler D. From the axles of traveler D depend hangers d,supporting at their lower ends a Weight W. The outward movement of the traveler is limited by engagement of the forward hangers CZ with the cross-piece b2, connecting the outer ends of sides o. To a tongue b3 on the free end of lever B is attached a rope E, that passes upward in front of and back over ad pending pulley e and thence extends to and around a depending pulley e,whence it drops, and has attached to its lower end a counter; weight W. A rope F, also attached to the free end of lever B, extends downward and over a pulley f, whil'e to the under side of weight W is attached a rope F. To the rear axle of traveler D is secured a rope G, that passes over pulleys g and g' and transmits the power exerted by weighted traveler D as it passes down over lever B.

In operating motion is communicated to traveler D by pulling upon rope F, so as to depress the free end of lever B. As soon as the movement of traveler D begins rope F is released, and the free end of lever B continues its downward movement under the pressure of traveler D. To restore the traveler to its normal position,'strain is exerted on rope F' until lever B assumes a horizontal position, and then the traveler is drawn back to 'the hinged end of the lever.

Figs. 3, 4, and 5 illustrate a modified con struction of my invention. In these figures, H indicates the supporting-posts, H an oscillating shaft journaled in said posts, and I I lever-arms having their inner ends rigidly secured Io shaft H. If preferable, one of the lever-arms may form a prolongation of the other, and shaft H may be a stationary arm about which the ends of the lever-arms move. Each of said lever-arms comprises a frame, the side bars 't' whereof form rails, between which run the wheels of the travelers K and K'. Beneath traveler K a weight W2 is supported by hangers depending from the axles of said traveler, and beneath traveler K' a weight V is also supported in a similar manner; but weight W3 is very much lighter than weight W2. Above shaft H is journaled a shaft H2, having on its outer end a drum H3 and on the inside of said drum a gear-wheel lar rope L' passes to and is wound around the Ioo inner part of said drum H3, said ropes being so attached to said drum that when one is wound up thereon the other is unwound.

In operating, the parts being in the position indicated by broken lines B2 of Fig. 3, traveler K being given an impulse outward gradually lowers and descends lever-arm I and imparts motion to power-rope M, attached to and adapted to be wound around drum H4, through rope L, drum H3, the train of gearing connected with drum H3, and drum H4. As the free end of lever-arm I descends the free end of lever-arm Il is raised, and traveler K' is drawn inward by rope L'. The outer end of lever-arm I is again raised and that of lever-arm I depressed through a rope N passing over pulley a, after which traveler K is drawn inward by traveler K descending lever-arm I. The descent of the free end of lever-arm I is retarded by a weight XW, to which is attached one end of a rope N, passing over a pulley n and having its other end secured to a lip t" on the free end of said lever-arm. rThe rope N is also secured to said lip 1l. The descent of the free end of leverarm I is further retarded by a weight W5, having attached thereto a rope N2, which passes over pulleys n2 and has an end attached to the carrier p of a running pulley P, that engages the under side of a rail R, attached to the side of said lever-arm by posts r and 0", which extend above the top of the lever-arm, post r being higher than post r, as shown.

I do not limit myself to the manner herein set forth ot' applying the power exerted by the descending traveler. Neither do I restrict myself to the other details of construction herein shown and described, as it is obvious that many changes may be made therein without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination,in a lnotor, of a leverarm having one end hinged to a support, a traveler adapted to move lengthwise of the lever-arm, the lever-arm being adapted to move under the weight of the traveler after a downward impulse is given the free end of said lever-arm, means for imparting a downward impulse to the free end of thelever-arm, means for raising the free end of the leverarm, means for automatically restoring the traveler to its normal position by the raising of the free end of the lever-arm, and a connection between the traveler and mechanism to which power is to be applied, for the purpose specified.

2. The combination, in a motor, of leverarms having their adjacent ends hinged to a support, a traveler on each of the lever-arms' and adapted to move lengthwise thereof, one of said travelers being of greater weight than the other, the lever-arms being adapted to be moved by the weight of the heavier traveler after a downward impulse is given the free end of the lever-arm carrying the same, means for imparting a downward impulse to the free end of the lever-arm carrying the heavier traveler, a connection between the travelers, whereby the movement of one traveler toward the free end of its lever-arm actuates the other traveler toward the hinged end of the other lever-arm, and a connection between the heavier traveler and mechanism to which power is to be applied, for the purpose specified.

3. The combination, in a motor, of leverarms set at a vertical angle the one with the other and having their adjacent ends rigidly connected with an oscillating su pport, a traveler on each of the lever-arms and adapted to move lengthwise thereof, one of said travelers being of greater weight than the other, the lever-arms being adapted to be moved by the weight of the heavier traveler after a downward impulse is given the free end of the lever-arm carrying the same, means for imparting a downward impulse to the free end of the lever-arm carrying the heavier traveler, a connection between the travelers, whereby the movement of one traveler toward the free end of its lever-arm actuates the other traveler toward the hinged end of theV other lever arm, and a connection between the heavier traveler and mechanism to which power is to be applied, for the purpose specilied.

4. The combination, in a motor, of leverarms set at a vertical angle the one with the other and having their adjacent ends rigidly connected with an oscillating support, a traveler on each of the lever-arms and adapted to move lengthwise thereof, one of said travelers being of greater weight than the other, the lever-arms being adapted to be moved by the weight of the heavier traveler after a downward impulse is given the free end of the lever-arm carrying the same, means for imparting a downward impulse to the free end of the lever-arm carrying the heavier traveler, a drum, ropes connecting the rear ends of the travelers with said drum and bcing wound in opposite directions about the same, and a connection between said drum and mechanism to which power is to be applied, for the purpose specified.
